Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where, and , is called the argument of z, .
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5. lies in 4th quadrant.
So, the trigonometric form is

Answer:
your answer will be 1
Step-by-step explanation:
Y = mx + b
slope(m) = -6
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -6(-4) + b
1 = 24 + b
1 - 24 = b
-23 = b
so ur equation is : y = -6x - 23
